Strengthening Partnerships in Renewable Energy

Tokyu Land Corporation, located in Shibuya, Tokyo, and i-Grid Solutions, headquartered in Minato, Tokyo, have taken a significant step forward in their collaborative efforts in the renewable energy sector. In November 2023, they signed a new agreement to enhance their partnership within the TLC VPP Joint Venture. This development comes after their successful initial goal of establishing 100MW of onsite Power Purchase Agreement (PPA) facilities within the first three years of their business collaboration.

Having realized their initial target, the companies have now set an additional goal to develop another 200MW of energy capacity, investing over 20 billion yen in new projects planned for the three years following 2026. This ambitious target, which will bring their total development to 300MW, highlights the effectiveness of their partnership and their mutual commitment to a sustainable energy future.

Background of the Collaboration

Japan's 7th Strategic Energy Plan sets a target for solar power to constitute 23-29% of the country's energy mix by 2040. Achieving this ambitious goal will require a remarkable increase, projecting a need for a growth factor exceeding three times the current capacity. Thus, both Tokyu Land and i-Grid are addressing this societal challenge through their joint efforts, aiming to accelerate the adoption of onsite PPA initiatives that have a lower environmental impact.

Promoting Onsite PPA Utilization

Tokyu Land has been advancing the development of renewable energy generation facilities across Japan since entering the renewable energy market in 2014. As of June 2025, they are engaged in 153 projects nationwide, which include 132 solar power projects, 15 wind power initiatives, 4 biomass projects, and 2 small hydropower plants, collectively yielding a capacity of 2,043MW. In preparation for the upcoming expiration of the Fixed Feed-in Tariff (FIT) system initiated in 2012, the company plans to focus on non-FIT project development, utilizing rooftop solar systems as a decentralized energy solution.

In contrast, i-Grid Solutions specializes in the implementation of onsite PPA projects primarily for commercial sectors such as retail and logistics, introducing solar power systems on facility rooftops without any initial costs. As of August 2025, they have achieved the installation of solar power facilities in 1,240 locations, generating a capacity of 305MW. i-Grid has also developed unique digital solutions aimed at maximizing solar panel installation areas and significantly increasing the self-consumption ratio of renewable energy.

The collaboration between Tokyu Land, which possesses one of Japan's leading renewable energy asset portfolios, and i-Grid, a pioneer in rooftop solar implementations, is expected to further energize the onsite PPA market in the country.
